CERN Courier article on Aston's research

Last year, Aston published a paper called “Is radioactive decay really exponential?” (Euro Phys Lett 97 52001).  The paper questioned the almost universally accepted belief that radioactive decay is always exponential.  He considered various arguments that suggest that slowly decaying isotopes may decay non-exponentially, which is hard to verify experimentally due to the long timescales involved.  This work was reviewed in a brief article in the CERN Courier.  The article invited both experimental and theoretical input from the scientific community.  The Cern Courier, established in 1959, reports news and events related to CERN’s high-energy physics community.
